Tennessee Titans defensive coordinator Jerry Gray said DL Shaun Smith is a "work in progress," as he continues to adjust to a 4-3 defensive scheme from the 3-4 system he worked in primarily during his days with the Kansas City Chiefs. "He's still adjusting," Gray said. "That's the good thing. When he stops adjusting, he's going to be in trouble. Because again, if you stop growing, that means you're not going what you're supposed to do. That's the good thing."
